Merge tag 'for-linus-4.15-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen fixes from Juergen Gross: "Two minor fixes for running as Xen dom0: - when built as 32 bit kernel on large machines the Xen LAPIC emulation should report a rather modern LAPIC in order to support enough APIC-Ids - The Xen LAPIC emulation is needed for dom0 only, so build it only for kernels supporting to run as Xen dom0" * tag 'for-linus-4.15-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen: XEN_ACPI_PROCESSOR is Dom0-only x86/Xen: don't report ancient LAPIC version
